As mourning relatives filed past her open coffin the supposedly dead woman suddenly woke up and started screaming as she realised where she was.

Fagliyu Mukametzyanova, 49, who was rushed to the hospital after collapsing in her home with chest pains, had been declared dead from a heart attack earlier that day by doctors in Kazan, Russia, a city of 1.14 million about 400 miles east of Moscow.

Waking up hysterical at her own funeral, Mukametzyanova lived for another 12 minutes, before dying for good.

The woman’s husband, Fagili Mukhametzyanov, 51, said, “I am very angry and want answers. She wasn’t dead when they said she was and they could have saved her.”

Minsalih Sahapov, a spokesman for the hospital, declined comment beyond stating that the hospital is carrying out an investigation.

After this, I’d wager doctors in Kazan are going to be extra careful from now on to double-check whether their patients are not just “almost dead,” but “all dead.”
